When printing an Outlook 2010 calendar overview (weekly) (with different colors in it) to a HP2320nf MFP, most of the colors will disappear, and a tan background will show.
When printing this same overview to an OKI printer, all is working fine.
When printing this same overview to a PDF, and then print the PDF to this same HP2320nf MFP, the colors are correct.
All the print previews are correct.
Latest driver is installed on the Windows 7 64bit machine.
Latest firmware is installed on the HP2320nf
Also tried the Universal Printer Drivers PCL5 + PCL6 (from Feb 2011) and also these have the same issue.
Any suggestions are welcome!
